changes are necessary for 240V applications.
For 208V applications, remove the red lead from
the 240V terminal and connect it to the 208V
terminal on the transformer. See Figure 5.

IMPORTANT!
This heat kit includes a transformer and relay
assembly. The transformer is factory-wired for
240V. For 208V, remove the red lead from the 240V
terminal and connect it to the 208V terminal on the
transformer. See step 6.
Failure to connect to the appropriate terminal can
cause the heat assembly to not operate properly.
